Analyzing air traffic performance with InfoBright and MonetDB
+0 Vote Up -0Vote Down

Accidentally me and Baron played with InfoBright (see http://www.mysqlperformanceblog.com/2009/09/29/quick-comparison-of-myisam-infobright-and-monetdb/) this week.

I decided it was time to actually give Infobright a try. They have an open-source community edition, which is crippled but not enough to matter for this test. The "Knowledge Grid" architecture seems ideal for the types of queries the client runs. But hey, why not also try
